Europe is “at risk,” he added, as he welcomed Ulf Kristersson, the prime minister of Sweden, the newest member of NATO. But Mr. Biden also said he remains “determined” that American soldiers will not be necessary to defend Europe. As a White House spokesman put it last week, it is “crystal clear” that the use of ground troops is off the table. But if such incursions were a genuine concern, then ground troops would be an option for the United States and its allies almost by definition. The rationale for NATO participation in the Russo-Ukrainian war is getting fuzzier at the very moment when one would expect it to be getting clearer.
